Fig. 14; is a section taken on line '14-14 Fig. 15 is a plan view of the chassis showing'a drag maintainer-installed thereon. Fig. 16 is a side elevation of Fig. 15.

The frame may be. of any suitable construction and is indicated as consistin of channel side members 20 and 21 and c annel cross members 22.

A motor 23 is suitably mounted on the frame and is provided with the usual transmission 24, hood 25, and radiator 26.v A suitable seat 27 is provided for the driver of the vehicle and is preferably mounted on springs.

The front wheels 28 are driven through universal joints 29'preferably of the ball and socket type which are vertically pi noted at 30 to permit steering of the vehicle. The axle housing 31 is of standard construction throughout with the exception of forwardly and rearwardly extending journals 32 and 33 which are integral with the differential m wheels consists of-the steeringlarms 39 and 40 which are fixed in-the knuc es 29 and are connected together at their outer ends by a connecting rod 41.- Integral with .lever 40 .is a ball joint 42. Integral with, and ex the knuck tendin to the left of the rear arm of the yoke 3 is a bracket 43 in which a vertical shaft 44 is rotatably mounted, the shaft having fixedly secured atvits'lower end, a'lever 45 provided at its outer endwith a ball joint 46, a connecting rod 47 coo erating between the ball joints 42-and 46. ixedto the ,upper end of shaft 44 is a worm gear 48 which cooperates with a worm 49, the gear and worm being: enclosed in a housing 50 which ismounted on the bracket 36. Worm 49 is secured on a shaft 51which is provided with suitable bearin s 52. The steering wheel 53 and steerin co umn 54ers of the usual construction t e steering wheel cooperating with shaft 51 suitable'means. Turning of the steering'wheel 53 rotates shaft 51 and coincidently worm'49 which 00- operates withiworm ear 48,-rotat in shaft 44 with lever 45,'whic through red. 4 .communicates the movement to the steering knuckles 29 the ball joints 42 and 46 permitting rocking motion of the frame relative to the axlehousing. f I

The rear axle housing 56 is of similar con struction to the front axles with the exce tion that the knuckles 57 are horizontal y pivoted to permit leaning of thewrea'r wheels 58 as indicated .by thedotted .lines, and thehousing is fixedly secured to the axlebracket 59" as indicated at 60. i

The leaning-mechanism consistsof the usual steerin arms 61 which are secured in is 57 which are wivoted at 62, the

arms 61 being connected together by a connectin' rod-63 which has a thread formed 'throug out a portion of its len th and on which a worm gear 64riS threade ly mounted on connectingrod 63 and cooperates with a a worm 65 which is secured on a vertical shaft 66 which has secured at its upper end a'hand wheel 67. The worm gear 64and' worml65 are mountedin a housing; 68 which-is vertical slidable as indicated at 69 andnon-rotatl aide, the shaft66being'slidable and rotatable in bearing j By rotating the handwheel 67,: wor m'gear 64 is rotated by cooperation with worm 65,

the worm gear 64" cooperating with the threaded connecting rod. 63 'and being sethrough bevel gears'55 or othercured against sidewise movement, will cause the wheels to lean as indicated by the dotted lines, the arcuate motion of the lever ends being compensated for by the sliding of the housing 64.

Thedrive for the front and rear wheels consists of the usual motor 23 and transmission 24' with drive shaft 71 which is coupled to a reversing shaft 72.

The driving box consists of a housing 73 in which the reversin shaft 72 is rotatably mounted and on whic a pair of bevel pinions 74 and 75 are rotatably and non-slidably mounted and which are rovided' with jaws to cooperate with a clutc block 76 which is slidab y and non-rotatably mounted on the shaft 72. A shifter fork 77 secured to a rod 78 cooperates'with the clutch block 76, and a shift lever 79 pivoted at '80 and cooperating with rod 78 at 81.

A bevel gear 82 is in constantmesh with pinions 74 and 7 5 and is adapted to be driven in opposite'directions respectively by these pinions, and is fixedly secured at one end of the rear drive-pinion shaft 83 and which is mounted in a suitable bearing 84, the shaft 83 driving the rear wheels through the usual drive pinion 85, 'master'gear86 and differential (not shown) axles 87, and through universal joints in the knuckles 57.

Thedrive for the front wheels is taken off shaft 83 through a pair of mitre gears 88 and 89, the gear 88.being fixed on shaft 83 and gear 89 being fixed on the'front wheel drive shaft 90 whichis suitably mounted in bearings 91 and 92 and provided with suitable universal joints 93, driving through a drive pinion 94 master gear 95, differential (not shown), shafts 96, through universal joints'in knuckles '29 to the front wheels 28.

I The draft frame is of substantiallytriangular construction, having backwardly diverging draftbars 97 and 98 and a transverse member '99 connecting the rearward ends of the bars. "A vertical shoe 100 is intermediately secured on the transverse member 99 for cooperation with the transverse adjusting the-front bracket 36. A cylindrical cap 106 having a flange 107 isbolted over the ball as indicated at 108. a i

The pin"101is"secured to the draft frame by clamping between cooperating clamp.

members 109, and by means ofbolts 111,

the shoulders 102 and 103 straddling the clamp members. Integral'with clamp members 109 and 110 are extensions 111 and 112 which are riveted to the draft bars 97 and 98. Bythis means universal adjustment of the draft frame .is permitted. I Transverse adjustment of the draft frame arrangement, angular and vertiealadjust ment of the draft frame is permittedurre spective of the transverse adjudinent', as the draft connection is universal. and the shoe 100 may assume any angular -1ie1ation to the nut 113. a Vertical iadjustmeiit'bf the draft frai'ne-is rovidedlthrough a crosa member 123 which 1s secured, to the draft frame -;and which is provided with ball seats .at ;its"o posite end to receive'the' ball endsa 124 0 adjusting screws 125, a pin'126 cooperating with'a slot in the ball seat to prevent rotation. ofthe screw.

A supporting member 127 which inay also be utilized as a motor support is secured across the top of frame side members and 21 and has a'spherical seat at each end. for

cooperation with aball member 128 which is also provided with a pin 1'29 cooperating with a ot 130 in the seat, to revent rotation of the member 128. Af brac ,et 131 integral with member 128 forms a bearing for the adjusting shaft 132.

The screw 1 25 is v slidable in ball member 128 and a 'mitre"gear 13'3 has a threaded bore cooperating with the screw." .A mating mitre car 134 is secured' on the; end of shaft 132. heother ends of shafts 132are fitted with mitrelgears" 135 and suitably-mounted in bearin 36" ab e universal joints 137. Cooperating, with mitre gears 134 are secured to the'handwhee1s'139 and and rotatable on stub shafts; secured in brackets 141. Shafts 132 are'also provided with telescopicmemberstorompensatefor ifierence in distance-between the centers ofjgears 133 and 138 due to transverse adjustment of the draft frame.
